During last week's dramatic "New York" episode, Bensimon was accused of having a nervous breakdown (which she now calls a "nervous breakthrough") after claiming her co-stars bullied her during a vacation to the Virgin Islands.

"I don't even need to know why people are ganging up on her," Staub, 47, told People.com at a book signing for her memoir, "The Naked Truth." "I can just say how it feels because no one has the right to put you down."

Staub can easily relate to Bensimon's position as the most disliked person on her reality show's cast.

Throughout all of the last season of "New Jersey," Staub was ostracized when her sordid past came back to haunt her after cast mates discovered she had been arrested for a number of felonies, including extortion, cocaine possession, and narcotics conspiracy. This season, her rivalry with her female cohorts has only intensified.

Though it has taken time for Staub to let her costars' comments "roll off her shoulder," she suggests that Bensimon needs to "block them out."

"Just go to a place inside of yourself and connect with your inner child in a fantasy," Staub said. "Keep living your life and don't apologize, sweetheart. I know how people can pour negative [energy] into you. So block it, Kelly, because you're beautiful and strong."

While she may not be on the best terms with her own cast mates, Staub said she can be a source of support for Bensimon, 42.

"I'm not being harsh towards those who are judging her, I'm trying to help her," she explained. "Bullying is every age and I do hope that somewhere in their season if this is happening that they make amends with her because not everyone can be on the outs like I can be. I'm okay being one in four. But if Kelly would need to talk, I'm right here."
